JOSEF HENRIK HALLBERG, OF NEW YORK, N. Y., ASSIGNOR TO GENERAL INGANDESCENT ARC LIGHT COMPANY, OF NEW YORK, N. Y., A CORPO- RATION.

REGULATOR FOR ALTERNATING SERIES ARC-"LIGHT SYSTEMS.

SPECIFICATION forming part of Letters Patent No. 728,570, dated May 19, 1903. Application filed September 80,1902. Serial No. 126,397. (No model.)

T0 at whom it may concern.-

Be it known, that I, J OSEF HENRIK HALL- BERG, a citizen of the United States, residing at New York city, county and State of New York, have invented certain new and useful Improvements in Regulators for Alternating Series Arc-Light Systems, of which the following is a specification.

My invention relatesto a device adapted to be connected in circuit with a generator of alternating currents and a series of arc-lamps, and which has for its purpose to increase the electromotive force of the current transmitted and also to maintain the current on the lamp-circuit constant.

The accompanying diagrams will serve to illustrate my invention, in which-- Figure 1 illustrates an arrangement in which a booster is used to modify the electromotive force, and Fig. 2 an arrangement in which a transformer is used to modify the electromotive force.

In the diagrams, 5 indicates a generator of alternating currents; 6 7, conductors leading therefrom, which are connected to the in terior of a regulator. The regulator consists of a case 8, partially filled with oil or otherinsulating fluid 9. Supported in the body of oil, through the instrumentality of a float 10, is a solenoid 11. This solenoid in Fig. 1 is connected at one end to the conductor 6 and at the opposite end to one terminal of the lamp-circuit 12 and in Fig. 2 at one end to the lamp-circuit 12 and at the opposite end to one terminal of the secondary of a transformer.

Situated in the bottom ofthe regulator-case is a body of laminated iron 13, having three legs 13" 13 13. The leg 13 is introduced into the cavity of the solenoid 11 and forms its core. Arranged on the body of iron, Fig. 1, are two coils 14: 15. These coils are connected as follows: one end of the coil 14: to the lamp-circuit and the other end to the conductor 7, one end of the coil 15 to the conductor 6 and the other end to the conductor 7; in Fig. 2, one end of the coil 14 to the solenoid 11 and the other end to the lamp-circuit and one end of the coil 15 to the conductor (3 and the other end to the conductor regulator.

7. These coils may be of different sizes of wire and so proportioned that the electromotive force of the lamp-circuit will be greater or less than that of the circuit from the generator 5, as desired. In the present case provision is made for increasing the current from, say, one thousand volts in the generator-circuit to two thousand volts in the lamp-circuit. The operation of the device is as follows: The current from the generator'5 is transmitted to the booster, Fig. 1, or transformer, Fig. 2, and therein modified and transmitted to the lamp-circuit. The current from the generator is also caused to traverse the solenoid 11. When all the lamps are operating in the lamp-circuit, no action will take place in the When, "however, one or more lamps are cut out of circuit, the solenoid 11 will move downward over the core 13", and the float 10 will displace an amount of liquid 9 in proportion to its immersion. The'effect of the movement downward of the solenoid 11 will be to introduce an impedance upon the lampcircuit in proportion to the change of resistance in the lamp-circuit due to the number of lamps cut out. 'This introduction of an impedance upon the lamp-circuit will not, however, in any wise alter the difference in electromotive force in the lamp-circuit from that in the generator-circuit produced by reason of the action of the booster or transformer.

I wish it understood that through the instrumentality of the booster or transformer, as stated, I may modify the current from the generator so that the current in the lamp-circuit will have a greater or'less electromotive force than that of the generator-circuit. This,

it will be understood, may be accomplished by well-known means.

I have shown my improved regulator provided with a floating impedance-coil and fixed modifying-coils. Manifestly other arrange ments could be used wherein the same results would be obtained-without altering the principle involved in effecting the modification or regulation-of the current.

Having thus described my invention, I claim 1. A regulator for alternating series arelight systems, comprising a body of iron, a

coil on said body of iron connected across the main conductors, a second coil on said body of iron, the ends of which are closed to form a circuit, a number of lamps connected in series with said coil, a solenoid also connected in series with said coil and adapted to be moved in relation to said body of iron to introduce or remove impedance from the circuit of said second coil and lamps, and means for counterbalancing the weight of the coil and the attractive influence exerted by the coil relative to the body of iron.

2. A regulator for alternating series arelight systems, comprising a body of iron, a coil on said body of iron connected across the main conductors, a second coil on said body of iron, a number of lamps in series with said coil, a solenoid in series with said coil and lamps, said solenoid adapted to introduce into or remove from the circuit of the coil and lamps an impedance, and means for overcoming the Weight of said solenoid and controllingits movementwhen influenced byits m agnetic attraction toward the body of iron.

3. A regulator for alternating series arclight systems, comprising a body of iron having upwardly-projecting portions, a coil on said body of iron connected across the main conductors, a second coil onsaid body of iron, a number of lamps in series with said coil, a solenoid in series with said coil and lamps and adapted to be moved relatively to one of said upwardly-projecting portions of said body of iron, and means for regulating the movement of said solenoid.

4. A regulator for alternating series arclight systems, comprising a body of iron shaped to form a closed magnetic core with upwardly-projecting portions, a primary coil thereon, a secondary coil thereon, a series of lamps and a solenoid in series with. the secondary coil and said solenoid adapted to move relatively to the upwardly projecting portions of said magnetic core, and means for controlling the movement of the solenoid relative to said core.

5. A regulator for alternating series arclight systems, comprising an inclosing case, a body of oil in said case, a floating body carrying a coil, a fixed magnetic body carrying coils, said coil on the floating body adapted when energized to modify the resistance of the circuit within which it is included to introduce or remove an impedance, and said coils upon the fixed magnetic body adapted to modify the potential of the current from the source of supply to the circuit in which the impedance device is included.

6. A regulator for alternating series arclight systems, comprising an inclosing case, a body of oil therein, a fixed magnetic body, a floating body, coils on said fixed magnetic body adapted to modify the potential of the current from the source of energy to the translating-circuit, and a coil on said floating body adapted to introduce or remove from the translatingcircuit an impedance in proportion to the resistance in said circuit.

7. A regulator for alternating series arclight systems, comprising a transformer in the generator-circuit having a portion of its core arranged to act as the core of a movable reactance-coil in the lamp-circuit, a movable reactance-coil in the lamp-circuit, and means for counterbalancing the eifective weight of the coil.

A regulator for alternating series arclight systems, comprising the combination in a single self-contained structure, of a transformer having its primary in the generatorcircuit and its secondary in the lamp-circuit, a movingreactance coil connected in the lamp-circuit, said transformer and reactancecoil having their cores formed from the same body of iron, and means for counterbalancing the effective Weight of the reactance-coil.

9. In a regulator, the combination of a fixed transformer, a movable reactance-coil, said transformer and coil having their cores formed from the same body of iron.

11. A regulator for modifying and regulating an alternating current fed to a translating-circuit, comprising a transformer, an impedance device connected in the secondary of said transformer, said transformer and impedance device having their cores formed from the same body of iron, and means for regulating the movement of the impedancedevice in accordance with the current demands of the translatin -circuit.
